PURPOSE: A backlight unit is provided to minimize the optical loss thereof. CONSTITUTION: A light guide plate(220) guides the light incident from a light emitting device, and includes a prism pattern. The prism pattern reflects light from a light reflection surface to the outside, and the light reflection surface faces an incident surface onto which the light of the light emitting device is projected. The prism pattern is formed in embossing or intaglio forms. |
